A senior adviser at the U.S. Treasury Department's Financial Crimes Enforcement Network, or FinCEN, was arrested Wednesday for passing along confidential suspicious activity reports on President Donald Trump's campaign manager Paul Manafort and others to reporters at the news organization BuzzFeed, U.S. Attorney Geoffrey Berman of the Southern District of New York announced.

According to prosecutors, Natalie Edwards' position at FinCEN gave her access to the sensitive documents issued by financial institutions under the Bank Secrecy Act for suspicious financial activity. From October 2017 to as recently as Oct. 15 of this year, Edwards allegedly provided an unnamed journalist details of SARs related to those involved in various ways to investigations into Russian interference in the 2016 elections.

According to details provided in the complaint against Edwards, the information corresponds to a dozen or so articles published by BuzzFeed News that all included reporter Jason Leopold's byline.

Federal officials claims Edwards passed along information related to Manafort and his deputy, Richard Gates, as well as transactions connected to the Russian embassy, alleged Russian spy Maria Butina, and Prevezon Alexander, who has been accused by federal prosecutors of money laundering. Both Manafort and Gates have agreed to cooperate with Special Counsel Robert Mueller's investigation into possible collusion between the Trump campaign and Russia.

Edwards was arrested in Virginia, according to the Manhattan U.S. Attorney's Office. In the complaint against her, federal officials claim that Edwards was interviewed on Oct. 16, during which she denied having contacts with the news media.

In a statement, Berman noted that SARs are confidential and that it is an “independent federal crime to disclose them outside of one's official duties.”

“We hope today's charges remind those in positions of trust within government agencies that the unlawful sharing of sensitive documents will not be tolerated and will be met with swift justice by this office,” the U.S. attorney said.

In a separate statement, Treasury Under Secretary Sigal Mandelker said the office “fully and proactively supported” the investigation of leaks by the Treasury's inspector general.

“Protecting sensitive information is one of our most critical responsibilities, and it is a role that we take very seriously,” Mandelker said.

A spokesman for BuzzFeed News declined to comment.

The BuzzFeed articles at issue have provided a steady inside account of financial activity in and around the wider universe of the Trump campaign's connections to Russia in 2016. During what prosecutors allege was the timeframe of Edwards' sharing, via pictures or descriptions sent over encrypted communications, BuzzFeed detailed allegations of suspicious wire transfers to Manafort in 2012 and 2013, dozens of payments made by the Russian Foreign Ministry to finance election work in 2016, and money allegedly funneled to Butina. In each, suspicious transactions were cited as the source for information in the stories.

Edwards is scheduled to be presented in U.S. District Court for the Eastern District of Virginia on Wednesday afternoon.
